Workers were included if they had been employed during 1975\u20131982 and had achieved at least 5 years tenure at the Montana site. Past fiber exposure was associated with an increased prevalence of parenchymal and pleural radiographic abnormalities. Smoking was not significantly related to the prevalence of small opacities. However, the number of workers who had never smoked was small, and this prevented measurement of the smoking effect. Under control for smoking and age, the prevalence of small opacities was significantly greater for vermiculite workers with greater than 100 fiber\/cc\u2010years exposure than for comparison groups (cement workers, blue collar workers, and coal miners) who had no known occupational fiber exposure. A logistic model predicted an increase of 1.3% in the odds ratio for small opacities at an additional exposure of 5 fiber\u2010years.<\/jats:p>","DOI":"10.1002\/ajim.4700110104","type":"journal-article","created":{"date-parts":[[2007,4,16]],"date-time":"2007-04-16T21:47:37Z","timestamp":1176760057000},"page":"27-37","source":"Crossref","is-referenced-by-count":36,"title":["The morbidity and mortality of vermiculite miners and millers exposed to tremolite\u2010actinolite: Part III.
